Using a temp folder by using OTF copying/burning would make things worse.

That also comes from experiencing trying it and wasting precious DL media. AFAIK OTF copying doesn’t use any temp folder. I used it and it goes from drive to drive assuming you have to burner in use. That how I do OTF copy but everything from the drive to the computer to the RAM and blank media must be in astrological aligment to work properly.
